The total subsidy provided to all generators of solar electricity last year is estimated to be about £1.2billion.

This was part of the £5.6billion subsidy paid to green energy producers, which critics say inflates household energy bills.

Figures from the Department for Business, Energy and Industrial Strategy (BEIS) following a Freedom of Information request show ten of the biggest solar farms in the country pocketed more than £2.5million each in eco-subsidy last year.

The payouts were offered to help increase the amount of ‘green’ energy produced in the UK.

The solar subsidy is responsible for around £15 a year on a household power bill.

The 200-acre site generated just over 54,000 MWh of electricity, worth around £2.5million, but was given a handout of £3.8million.

The farm is owned by Cubico Sustainable Investments, which has seven other smaller solar farms in England.

The nation’s largest installation, Shotwick Solar Park, in Deeside, North Wales, was handed a £3.5million subsidy, which was pocketed by owner Foresight Solar Fund.

It also generated electricity worth around £2.5million.

Dr Lee Moroney, of the Renewable Energy Foundation charity, said: ‘The moratorium on new subsidies to renewables was the right thing to do, but it is a classic case of shutting the stable door after the horse has bolted.

‘The legacy subsidies are themselves so high … that Government must consider retrospective cuts to reduce what is an unreasonable burden on the consumer and the wider economy.’

The Solar Trade Association said: ‘Like all new technologies solar needed support in the early days to get off the ground … Today solar doesn’t need any significant subsidy at all.’

A spokesman for BEIS said: ‘The UK is leading the world in cutting emissions … Government support has kick-started the UK’s solar industry enabling the costs of solar to reduce dramatically, so that solar can eventually stand on its own, subsidy free.’
